E85 smoothed out my cold starts??

falconey · 06-02-2014, 07:38 AM

So I pumped in my first 3 gallons of E85 on Friday so I've had three overnight cold starts since adding the E85 and my cold starts are a lot smoother than when I was only used 93. Anyone have an explanation for this? Prior to adding E85 I'd have rough idle for about 30-45 secs;based on my research could potentially be a bad injector.

Obviously this isn't anything serious, I was just curious if there was an explanation.

I just recently switched to my E25 map and I've noticed the same thing. It's also smoothed out my hiccup at idle when car is at full operating temp. The car just loves this stuff.

Did you reset adaptions through INPA? After I added E85 and reset adaptions mine virtually went away.
